Molluscum Contagiosum infection associated with pimecrolimus use in Pityriasis Alba

Atopic dermatitis is an inflammatory, chronically relapsing, highly pruritic skin disorder that has considerable impact on the quality of life. As corticosteroids are not ideal for long-term control of the disease because of their potential side effects, steroid-free topical immunomodulators have recently been developed for the treatment of atopic dermatitis. Although clinical trials do not indicate an increased risk of cutaneous infection, the clinician must be careful about viral infections such as eczema herpeticum or molluscum eczema that can be observed during treatment with pimecrolimus and tacrolimus. We report molluscum contagiosum that developed on the preauricular area treated with topical pimecrolimus.
